> like how copying and pasting any multiline document into your browser's URL bar will almost certainly format it into a sane single-line format.

Didn't know that. I learned the other day that one can paste a password into the URL bar and drag it to a password field on the website that's annoyingly blocking paste (on Firefox at least). Probably a bad idea for security reasons (telemetry?). Just found it surprising. Also noticed many crappy sites that block paste will forget to block Ctrl + insert or Ctrl + Shift + v. I usually don't have this problem because the plugin of my password manager usually works..

You could probably drag it directly from the password manager to the password field, instead of using the URL bar as an intermediate (which indeed is a bad idea as whatever you enter there usually gets sent somewhere).
